**3.1 Most important cashmere-producing breeds**

From a biological viewpoint, all of the dairy goats produce cashmere, but in some breed the production of cashmere is noticeable, so they have been nomenclatured as "cashmere-producing goats." Indeed, many breeds of goat have secondary follicles in their skin that produce "down coat" or cashmere. But the amount of this cashmere is very different among breeds. So, from each goat, we can harvest cashmere, but its quantity may be 10–500 gr/animals. In conclusion, the breeds with sufficient quantity of down fibers will be famous as cashmere goats. For example, some breeds are shown in **Figures 4–6**. In the literature, various words could be found for cashmere, e.g., Kork, Tuvet, and pashmina. Cashmere goat is named as Tibet goat in some bibliographies. Some cashmere-producing goats are Nningza, Soyan, Gansu, and Raeini. The wild goat of *Capra hircus blythi* found in Sind and Baluchistan is probably a ascendant of cashmere goats.
